"FACT: "Bubby the Burger Town Boy" is the animatronic mascot at all drive-thru locations."

— In-game description

Bubby[1] (known as "murderbot" in the game files) is the Burger Town mascot, featured in the Call of Duty: Advanced WarfareExo Zombies map Infection. The achievement MEAT IS MURDER requires the player to activate Bubby as part of the Easter egg. Activating Bubby will result in one of two events: he will either simply explode, or help the player kill zombies for one round. However, he will subsequently explode when the round ends.
